Biometric Patient Identity Verification System

ABSTRACT

A system for determining identification of a patient communicating over a computer network with a medical provider with certainty is provided using biometric data captured by said medical provider with subsequent biometric data generated by biometric sensors proximal to a patient. Using previously captured biometric information concerning physical characteristics unique to the patient and comparing such to subsequently generated biometric data from the patient, a medical provider can determine the identity of a patient attempting communication over a computer network with the medical provider.

FIELD OF THE INVENTION

The present device relates to patient identification during remote health monitoring. More particularly, the method and apparatus herein relates to a system for capturing a plurality of biometric identifiers of a patient which are communicated to a remote health provider and verified prior to subsequent communication of health information of that patient.

BACKGROUND OF THE INVENTION

With the evolution of personal computing device and smartphones and pad computers and the like in recent years, advances have been achieved in the ability for patients to ascertain health conditions as well as problems remotely. Through the employment of biometric sensors and monitoring devices which are in wired or wireless communication with a computing device running software adapted to the task of converting received sensor data to conventional test outputs, patients can monitor or test themselves for a wide variety of health issues.

Such computing devices in recent years have evolved to be able to communicate data over wireless and wired networks, to virtually any point on the globe. As a consequence, physicians and medical providers have been provided with a valuable means to actually monitor patients and their health conditions in real time rather than just examining such patients on rare or even scheduled visits to the health provider. As can be discerned, the ability to test and monitor patients for known or suspected health conditions remotely and frequently, provides an exceptionally valuable tool to physicians and health providers in the monitoring of known health conditions as well as in testing over time durations for diagnosing unknown but suspected health conditions.

For example, a heart patient having suspected heart rhythm disturbance called bardycardia, where the heartbeat slows, may actually present in an office visit after the exercise provided by walking through parking lots and hallways, as having a normal heartbeat. However, upon arriving home and relaxing, the condition may return and if not diagnosed and treated promptly, can cause severe problems such as hypoxia and even life threatening issues. There are many such conditions which are not conclusively ascertainable by the physician during a visit by the patient to the medical facility. The ability of the patient thus, to remotely test for a suspected condition over time and provide results to the physician of such testing, is consequently a valuable tool in the early and accurate diagnosis of a health problem which appears inconsistently.

However, issues exist concerning the provision of such testing data from the patient in remote locations. First and foremost for the physician is the proper identification of the patient identity before employing the transmitted testing data from a remote source. Should the data from the wrong patient be communicated and employed for a different patient, the physician can make a diagnosis resulting in great harm to the patient to which the wrong data is applied. Further, in some cases, patients have been known to fraudulently submit testing data from other persons as their own. As such, it is critical that the physician or medical service provider, receiving a data stream correlating to a health condition test, be certain, without any doubt, that the data received relates only to a single patient.

The system herein provides a method for positively identifying data or a data stream communicated to a remote medical provider, as being specifically related to a single person or patient. Using one or preferably a plurality of biometric readings from a patient, which when electronically communicated to the medical provider, the identity of the patient may be confirmed with certainty by comparing the transmitted biometric readings to stored such readings which are pre authenticated as matching a single patient. It thus provides medical providers a means to ascertain, with certainty, that the medical testing data being communicated over a network to that medical provider, is associated and concerns only one possible patient. Further, the system prevents fraudulent medical testing or monitoring information from being transmitted to the medical provider over the network either intentionally by the patient or unintentionally by third parties.

The forgoing background and examples of patient authentication through the employment of biometric readings are intended to be illustrative and not exclusive, and they do not imply any limitations on the invention described and claimed herein. Various other limitations of the related art are known or will become apparent to those skilled in the art upon a reading and understanding of the specification below and the accompanying drawings.

SUMMARY OF THE INVENTION

The system herein employs biometric sensing components providing data concerning the health of a patient which can be transmitted over a computer network. Using sensed biometric information about a patient sending electronic information to a medical provider over a network, medical providers and physicians can identify the patient with certainty and employ the communicated testing information only for the correctly identified patient. In this manner medical providers can employ the communicated information only to the correctly identified patient and also be assured that the data communicated is not fraudulent or gathered from another individual. It thus provides medical providers with certainty as to the identification of the patient and that the data being communicated is only from that patient.

In the system, each patient is subjected to standardized biometric testing for one or preferably a plurality of medical biometric readings of a patient that can only be associated with that individual patient. For example the electrocardiogram (EKG) of individual when traced on paper or a display, is a reliable identifier of each individual patient. This is because each heart beats uniquely and generates an EKG trace which can be associated with the individual patient. Thus, an EKG of a patient taken during an office visit can be stored in electronic memory associated with that individual patient and act as an electronic identifier of that individual patient at a later date by comparing the stored EKG to one taken in real time remotely. Another biometric identifier is a fingerprint, which can be digitized to an electronic fingerprint file and stored in electronic memory in association with an individual patient. Subsequently, an electronic fingerprint inputs from a fingerprint sensor remotely from the patient, can be matched to the stored electronic fingerprint to ascertain a match and the identity of the patient.

Another biometric identifier unique to a patient is an iris scan. In the system an iris scan of the patient is digitized and stored in the electronic memory of a database as matching an individual patient. Subsequently, a remote image capturing device such as an electronic camera or cell phone camera can capture the iris image of a patient, and communicated over a network to a medical provider. The received digitized image communicated by the patient can then be compared with the digitized image stored in electronic memory associated with a patient to ascertain a match to confirm the identity of the patient sending the image.

Another biometric identifier employable in the system herein, is a digital image of capillaries of an individual finger of a patient captured using a pulse oximiter device with an image capturing and transmitting component. Every patient has a unique pattern to the capillaries in each finger upon which a pulse oximiter is engaged to ascertain heart rate and oxygen saturation of the bloodstream. In the system herein, during a visit to the medical provider, a biometric reading of an image of the capillaries of one or a plurality of fingers is captured and digitized and associated with the individual patient. Subsequently, the patient will employ a biometric sensor engaged to a networked computing device, such as a capillary image capturing pulse oximiter, to capture a digital image of the capillary pattern of a chosen finger. That digitized capillary image is then transmitted to the medical provider and compared with the digitized capillary image or images associated with the purported individual patient. A match will authenticate the patient sending the digitized capillary image over a network such as the internet, as the known patient.

As such, in the system herein, one, or more preferably a plurality of digitized biometric readings of a patient are taken using biometric sensors remotely, digitized, and then communicated to a medical provider as a means to first identify the patient with certainty. Only thereafter will testing telemetry or digitized information concerning medical monitoring or testing, communicated remotely over a network from the computing device of the patient, be associated to the patient identified using the digitized matching, and thereby used for diagnosis by the medical provider.

An additional layer of security may be provided in a manner to prevent patients or imposters of patients, from storing digitized iris images, capillary images, or fingerprints, and then communicating such to the medical provider to authenticate a user. In this mode of the system, software running on the computing device of the medical provider, can transmit a time stamp to be included in metadata of each digitized file sent by the patient during authentication. In this fashion, only a real time capturing of biometric attributes of the patient will be enabled to insert the time stamp in meta data or digitized imaging of the biometric attribute of the patient being requested by the medical provider and subsequently sent by the networked computing device of the patient. Additionally, software running on the medical provider computing device in communication over the network with the patient computing device may designate a plurality of biometric readings of individual patient physical or biological characteristics to be sent by the patient device using local biometric sensors, in a particular order of the plurality requested.

BRIEF DESCRIPTION OF DRAWING FIGURES

The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate some, but not the only or exclusive examples of embodiments and/or features of the disclosed biometric patient identity verification system. It is intended that the embodiments and FIGURES disclosed herein are to be considered illustrative of the invention herein, rather than limiting in any fashion. In the drawings:

FIG. 1 depicts a flow chart of method and apparatus for biometric patient identity verification for communications over a network between a medical provider and patient.

DETAILED DESCRIPTION OF THE INVENTION

In this description, the directional prepositions of up, upwardly, down, downwardly, front, back, top, upper, bottom, lower, left, right and other such terms refer to the device as it is oriented and appears in the drawings and are used for convenience only and such are not intended to be limiting or to imply that the device has to be used or positioned in any particular orientation.

Now referring to the flow chart in FIG. 1, there is seen a generalized flow chart of the system 10 herein for determining patient identification prior to communications from patients with medical providers over a network. Such communications for example can occur where patients are remotely monitoring a medical condition or monitoring a body function over time and communicating captured information in electronic form to a medical provider. For example a patient with inconsistent symptoms of a heart problem, which are not easily determined in a simple office visit, can be provided with monitoring equipment or software adapted to monitor a medical condition using a smartphone or computer, and communicate testing results electronically over a time duration.

Also by example, but in no way limiting, is monitoring for sleep apnea. Such is not easily done in sleep centers because patients are kept awake by unfamiliar surroundings and noise so an electronic home monitoring device is preferably employed to monitor sleep at home over a duration of evenings. In such cases the patient could use the testing equipment to capture sleep apnea readings which may be communicated to the health provider over a network connection from the device itself or a user computing device. Of course, any condition that may be tested or remotely monitored electronically and reported electronically to the medical provider is anticipated within the scope of this system, so long as the patient identity sending the electronic information can first be determined without doubt, using digitized biometric information concerning the patient captured remotely.

In a first step in the system 12 during a visit to the medical provider such as a doctor or medical facility, patient identification information would be obtained, including but not limited to legal identification, address, contact information, insurance information, and other relevant patient identification information. The patient would generally be assigned or associated with a patient identifier which may be alphanumeric or otherwise.

In a next step in the system 14 this patient identification information in an association with the patient identifier, is stored in electronic memory accessible to the computing device of the medical provider. This patient identifier and patient identification information is employed and added to so long as the patient is served by the medical provider.

In a following or third step 16, at the facility of the medical provider or an affiliated facility, biometric sensors are employed to capture biometric readings of one or a plurality of patient physical or body or health or functional characteristics. Such biometric sensors may include one or a combination of a digital fingerprint capturing device, a pulse oximiter, an imaging device to capture the capillary pattern formed by capillaries in a finger of the patient, an imaging device to capture the iris of the eye, and an electrocardiograph machine. The electronic signal of the image or electrical performance of the body part captured by the biometric sensor, is communicated to a computing device and digitized into a digital identifier of the respective body part imaged or captured or tracked electronically.

In the case of a biometric sensor, in the form of a digital fingerprint capturing device, it will generate a digital image of a fingerprint which may later be compared. A biometric sensor provided by a pulse oximiter may be combined with an imaging device which will employ the light transmitted through a finger, to capture a digital image of a capillary pattern formed by capillaries in a finger, which may later be compared to another such capillary pattern image. In the case of a biometric sensor for imaging the iris of the eye, a digital image is generated which may later be employed for comparison to a subsequent iris digital image.

In the case of a biometric senor, which generates an EKG, the electrical impulse (or “wave”) travels through the heart will conventionally show a line graph depicting the timing of the top and lower chambers where a P-wave is generated by the upper chambers and a QRS complex is generated by the right and left bottom chambers, followed by a T-wave generated during recovery or return to a resting state for the ventricles. This resulting EKG can be like an electronic heart fingerprint and highly identifiable to individual patients. When digitized, the EKG can later be employed in comparison to a transmitted EKG taken remotely in identifying the patient.

As noted, in this third step 16, each biometric sensor will generate a respective biometric reading of a particular physical characteristic of the patient, which is digitized and stored in electronic memory as associated with a single patient.

In a following or fourth step 18, when a patient having an identifier and biometric readings associated with that patient, initiates electronic communication from a patient computing device or a testing device in their possession, over an electronic network such as the internet, the computing device of the medical provider will first seek validation of the patients identification. To that end, prior to allowing communication of test or monitoring data from the patient, software running on the computing device of the medical provider, will require the patient to employ patient biometric sensors in the location of the patient, and to capture current biometric readings of one or a plurality of patient physical characteristics or functions and to communicate digitized output of the biometric sensors, over the network to the medical provider computing device.

The same biometric sensors employed by the medical provider in the third step 16 are employed at this remote location of the patient at this subsequent time. Preferably, the patient is required to communicate digitized readings from at least two of the biometric sensors such as any two from the group including a digital fingerprint capturing device, an imaging device to capture the capillary pattern formed by capillaries in a finger of the patient, an imaging device to capture the iris of the eye, or a digitized EKG from a one or more lead electrocardiograph which are currently available for engagement to computers and cell phones.

Upon receipt of the digitized current captured biometric readings of from the patient biometric sensors, in a comparison step 20, such are compared with the digitized identifier biometric readings captured by the medical provider in step 16 and stored in as identifier biometric readings in electronic memory.

In a step subsequent 22, if a match between captured biometric readings and the identifier biometric readings is determined, the identification of the patient is determined as a match and electronic communications from the patient computing device or a testing device in their possession, will be accepted by the medical provider computing device and stored in electronic memory in association with the patient identifier for use by physicians and staff.

An optional step 24, a marker or time-stamp requirement may also be implemented after step 20 but before step 22, in order to prevent a party from storing pre-captured biometric readings using biometric sensors on the patient, and storing them to send when requested in step 18. In this step 24, a digital time stamp, is communicated from the medical provider computing device which is required to be included in meta data or as part of the digitized files sent by the patient in response to step 18 for such biometric digital information. In this step, should the time stamp not be included in the digitized biometric readings, a match 22 will not be ascertained and communication denied. Also in this step, the response from the patient may be required to occur within a time duration such as 2-5 minutes to give them time to generate biometric readings but not substitute files.

While the present system has been described herein with reference to particular embodiments thereof and/or steps in the method of production or use, a latitude of modifications, various changes and substitutions are intended in the foregoing disclosure, and it will be appreciated that in some instance some features, or configurations, of the invention could be employed without a corresponding use of other features without departing from the scope of the invention as set forth in the following claims.
